Popis: Magadi soda (MS) is a commercially available form of sodium sesquicarbonate in Kenya. Soaking high-tannin sorghum (HTS) grain (2.5% catechin equivalents) in a 6 g l−1 MS solution was shown to eliminate measurable tannin content. A feeding trial was conducted to investigate the performance of broiler chicks fed soyabean-based diets containing HTS or MS-treated HTS as the sole cereal source from 1–3 weeks of age. A third diet containing sorghum with no detectable tannin content served as the control. Diets containing 220 g kg−1 crude protein were fed to 6 pens of 5 birds per pen for each treatment from 1–2 weeks of age and to 4 pens of 4 birds per pen per treatment in weeks 2–3. Feed intake, weight gain and feed efficiency (FE) were determined weekly. Apparent dry matter digestibility (DMD), metabolizable energy (AMEn) and nitrogen retention (NR) were measured over the last 3 days of each period. Gain and feed intake were not affected by treatment (P>0.05), but FE and DMD were lower (P
